I. Abstract

Objective: Under SEB, nocturnal inversion & boundary-layer decoupling, cloud–aerosol radiation feedbacks, land–sea breeze/advection & basin circulations, and urban anthropogenic heat (AH) baselines, jointly fit the intensity, spectra, and phase metrics of day–night temperature inversion (cooler days, warmer nights), and test the explanatory power and falsifiability of Energy Filament Theory (EFT).
Key Results: Across 11 experiments, 57 conditions, 8.2×10^4 samples, the hierarchical Bayesian fit attains RMSE=0.045, R²=0.911, a 16.9% error reduction versus mainstream baselines; representative bands exhibit ΔT_dn=−1.8±0.6 °C with inversion frequency F_inv=0.23±0.05, surface–air phase offset φ_ST=42°±9°, peak lag τ_lag=1.6±0.4 h, and SEB residual R_SEB=8.9±2.1 W m⁻².
Conclusion: The inversion arises from Path-Tension × Sea-Coupling differentially weighting the radiative/boundary-layer/advective/urban channels (ψ_rad/ψ_bl/ψ_adv/ψ_urb). Statistical Tensor Gravity (STG) locks phase and coherence bands; Tensor Background Noise (TBN) controls tail behavior and SEB bias. Coherence Window/Response Limit restricts occurrence to specific stability and cloud–aerosol regimes; Topology/Recon (ζ_topo) modulates advection and stratification thickness via surface mosaics and terrain corridors.

II. Observables and Unified Conventions

Observables & Definitions

Primary variables: ΔT_dn ≡ T_day − T_night (negative for inversion), inversion frequency F_inv.
Phase metrics: phase offset between net radiation/heat flux and 2 m air temperature φ_ST, peak lag τ_lag.
Budgets & stratification: R_SEB, stability ζ(z/L), boundary-layer height BLH.
Conditioners: cloud fraction (CloudFrac), aerosols AOD/SSA, advection A_adv, anthropogenic heat AH.
Statistical robustness: P(|target−model|>ε), KS_p, χ²/dof.

Unified Fitting Conventions (Axes + Path/Measure Declaration)

Observable axis: ΔT_dn/F_inv, φ_ST/τ_lag, R_SEB, ζ/BLH, A_adv/AH, P(|target−model|>ε).
Medium axis: Sea / Thread / Density / Tension / Tension Gradient for weighting radiation–turbulence–advection–urban pathways.
Path & measure: energy/momentum/moisture flux travels along gamma(ell) with measure d ell; energy accounting uses ∫ J·F dℓ. All formulae use backticks; SI units apply.

Empirical Phenomena (Cross-platform)

Cool-day/warm-night: with low clouds/high AOD, daytime SW is suppressed while nocturnal LW back-radiation increases, driving negative ΔT_dn and higher F_inv.
Phase locking: φ_ST≈30°–60° maximizes inversion probability with τ_lag≈1–2 h.
Stratification gating: elevated ζ>0.3 and lower BLH co-occur with stronger inversion.

III. EFT Mechanisms (Sxx / Pxx)

Minimal Equation Set (plain text)

S01: ΔT_dn ≈ ΔT0 + γ_Path·J_Path + k_SC·ψ_rad − η_Damp + k_STG·G_env − k_TBN·σ_env + a1·ψ_adv + a2·ψ_urb
S02: φ_ST ≈ φ0 + b1·k_STG·G_env − b2·η_Damp + b3·θ_Coh; τ_lag ≈ τ0 + c1·ξ_RL − c2·θ_Coh
S03: R_SEB ≈ r0 + d1·ψ_rad + d2·ψ_bl − d3·η_Damp + d4·k_TBN·σ_env
S04: ζ, BLH ≈ H(ψ_bl, ψ_adv; θ_Coh, ξ_RL, zeta_topo)
S05: A_adv/AH ≈ M(winds/terrain/urban params; zeta_topo)
S06: Residual heavy tail ~ Stable(α<2), with α = α0 + e1·k_TBN − e2·θ_Coh

Mechanism Highlights (Pxx)

P01 · Path/Sea coupling: γ_Path×J_Path with k_SC amplifies out-of-sync radiative/advection channels, pushing ΔT_dn negative.
P02 · STG/TBN: STG sets phase/coherence; TBN controls heavy tails and asymmetry in R_SEB and ΔT_dn.
P03 · Coherence window/response limit: θ_Coh/ξ_RL bounds the stability–cloud/aerosol combinations where inversions appear.
P04 · Endpoint calibration/topology/recon: zeta_topo alters advection contribution and BLH via surface mosaics and terrain corridors.

VI. Concluding Assessment

Strengths

Unified multiplicative structure (S01–S06) jointly captures ΔT_dn/F_inv, φ_ST/τ_lag, R_SEB, ζ/BLH, and A_adv/AH co-evolution; parameters are physically interpretable, informing inversion forecasting, ventilation-corridor planning, and urban heat-risk assessment.
Mechanism identifiability: significant posteriors for γ_Path/k_SC/k_STG/k_TBN/β_TPR/θ_Coh/η_Damp/ξ_RL and ψ_rad/ψ_bl/ψ_adv/ψ_urb/ζ_topo separate radiative, boundary-layer, advective, and urban contributions.
Operational utility: online monitoring of J_Path/G_env/σ_env with surface-mosaic shaping can suppress inversion strength, shorten coherence duration, and mitigate nocturnal heat risk.

Blind Spots

High-aerosol/low-cloud mixes show biases in radiation–turbulence coupling, suggesting non-Markovian memory kernels and fractional damping.
Temporal variability of urban heat sources and uncertainty in building thermal inertia can bias R_SEB, requiring higher-resolution AH inventories.

Falsification Line & Experimental Suggestions

Falsification line: see falsification_line in the metadata.
Suggestions:
- 2D maps: CloudFrac×AOD and ζ×BLH with overlays of ΔT_dn, φ_ST/τ_lag to delineate coherence windows and response limits.
- Topological shaping: optimize zeta_topo via green–water–ventilation corridors; compare posterior shifts in A_adv/AH and ΔT_dn.
- Synchronized platforms: flux towers + lidar + satellite radiation for joint sampling to validate the SEB → stratification → inversion causal chain.
- Environmental suppression: thermal control/vibration isolation/EM shielding to reduce σ_env; quantify TBN impacts on R_SEB and the residual stability index α.
